Background: The purpose of this study was to determine the effectiveness of percutaneously place self-expanding metallic stent for the relief of biliary obstruction in patients with hilar cholangiocarcinoma. Materials and Methods: From November 2001 to December 2004, 48 patients with hilar cholangiocarcinoma were prospectively studied. After percutaneous placement of bilateral self-expanding, uncovered metallic stents, follow-up evaluation was carried out until July 2005. Results: There were 4 cased of Bismuth type Ⅱ,21 cases of Bismuth typeⅢa 8 cases of Bismuth type Ⅲb and 15 cases of Bismuth type Ⅳ. Stent placement was technically successful in all patients All patients had satisfactory biliary drainage, resulting in one week drainage rate of 72.8% and final drainage of 91.9% There were 12 cases (21.3%) of abdominal pain requiring analgesics and 1 case (7.1%) of cholangitis; both were successfully managed with conservative treatments. Late complications occurred in four patient (8.3%), including two patients with cholangitis, one patient with liver abscess, and one patient with biloma; all were appropriately managed by percutaneous drainage. The average length and median durations of stent patency and median survival time were 303 days (range, 60~815) and 338 days (range, 60 ~1175), respectively. Conclusion: Placement of a percutaneous metallic stent is an effective and safe method of palliation of patients with hilar cholangiocarcinoma.

This study was aimed at searching for improvement strategies of the Industrial Technology Teacher In-service Training Program at C.N.U. The data were gathered from the questionaires received from 180 teachers who attended the in-service teacher training program conducted by the Industrial Education College of C.N.U. from July 13, 1981 to August 15, 1981. The findings of this study were : 1. All industrial technology teachers should participate in Industrial Technology classes during the in-service training program regardless of their difference in subjects of their Teacher Qualification Certificate. 2. The present time ratio of theory and practice (70 : 30) in major subject area should be revised to 60 : 40. 3. It is desirable that teachers receiving training should be able to choose their training subjects. 4. The training content should be constructed to be in congruence with the secondary school curriculum. 5. The field trip/industry visitation should be more emphasized than it was done so far.

Generally, shear wall system appears to resist the lateral loads, because high-rise buildings require satisfaction of building drift limit due to lateral loads. However shear wall system used mostly concrete, in this paper steel plate shear wall use to resist the lateral loads instead of reinforced concrete wall system. But, there is lack of research and understanding of steel plate shear wall system so that no real building of such system exists in Korea. This paper demonstrates stability and serviceability of steel plate shear wall by preliminary experimental test.

웹 기반 가상현실 프로그램이 초등학생의 공간시각화 능력 향상에 미치는 효과

공간 능력 및 공간 시각화 능력의 향상은 우리가 살고 있는 세계를 표현하고 설명하는데 도움을 주고 실생활과 작업에 관련된 문제해결 능력을 기를 수 있게 한다. 제 7차 수학과 교육과정에서 공간 능력 및 공간 시각화 능력을 향상시키기 위한 학습으로 구체적 조작물과 학습지 사용을 병행하고 있다. 하지만 초등 기하는 공간적인 경험을 현실 상황이나 구체물 조작을 통하여 형성된 공간직관을 수학화하도록 하여야 하나, 실제 현장에서는 학교여건 등의 여러 실정으로 조작 자료들이 제대로 마련되어 있지 않거나 잘 사용하지 않고 있다. 이에 본 연구에서는 이런 요구에 의해 아동과의 상호 작용성과 접근성을 향상시킨 웹 기반 가상현실 프로그램을 개발하고 그 효과를 분석하였다. Spatial assembly skills and spatial visualization skills help us to express the world we are living in and to develop problem-solving abilities related to real life and professions. The 7th Mathematics Curriculum use specific tools and learning materials to improve spatial skills and spatial visualization skills. However, though elementary geometry is supposed to archive spatial experiences or spatial intuitions formed by manipulating real situations and specific tools, actual classrooms do not have or do not often use sufficient manipulative materials due to school's conditions etc. To meet such demands, this study aims to develop a web-based virtual reality program with improved internationality with children and accessibility, and to diagnose the possibility of a web-based virtual reality study program through the analysis of the effect.

Objective : There are controversies in pnmmg technique of rocuronium whether it can or can't shorten the onset time. We want to compare the effects of two different priming doses and intervals of rocuronium. Materials and Methods : After giving propofol, 50 patients were randomly assigned to 5 groups. Group I received a placebo, followed 3 min later by rocuronium 0.6 mg/kg. Priming doses and intervals of Group II, Ill, N, V were 0.06 rng/kg and 2 min, 0.12 mg/kg and 2 min, 0.06 rug/kg and 3 min, 0.12 mg/kg and 3 min, respectively. Total dose of rocuronium was 0.6mg/kg. Train of four (TOF) count or ratio and 1st twitch height of TOF (T1) were monitored with 15 secondsintervals. TOF ratio of each groups just before bolus injection, duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were compared. Results : Duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were decreased in priming groups compared to Group 1 (P < 0.01) In group V, significant depression of TOF ratio just before bolus injection was seen (P < 0.05). Conclusion : Priming technique with rocuronium is effective method to shorten the onset of neuromuscular block. But priming dose of rocuronium itself could cause hypoxia and aspiration in awake patients and should be used carefully. Priming dose of rocuronium 0.06 mg/kg and 2 minutes interval maybe relatively safe method.

Disposal of a homicide victim by dismemberment is rare, but individual cases are on record in most major medicolegal departments. Recognition of postmortem mutilation may be of importance in the interpretation of certain murders committed by sexual perverts and other mentally deranged individuals and sometimes performed for the sole reason of easier disposal of the body. Postmortem dismemberment is usually readily recognizable as such; The edges of the injuries are dry and lack evidence of bleeding. The joints may be disarticulated without fracture, or the use of an axe or saw may be evident from examination of bones. Parallel horizontal or oblique furrows in the bone surface are caused by skipping of the saw prior to establishing depth. Such patterns on the bone may assist in identifying the particular saw involved. So we report 25 dismembered corpses that autopsied in National Institute of Scientific Investigation. This paper can help in attempting to establish not only the first criminal investigation steps but also the medicolegal approach methods in unidentified and dismembered deaths.

The purpose of this study was to investigate the remodeling process of the streptozotocin-induced diabetic rat's resected condyle. This experiment was performed with male Sprague-Dawly strain rats weighing approximately 250gm, which were rendered diabetic by an intravenous injection of streptozotocin(70 ㎎/㎏ body weight). After condylectomy, experimental rats were serially terminated on the 1st week, the 2nd week, the 3rd week, and the 4th week. The following termination, the mandibles were dissected out to make specimens. Each mandibular condyle was radiographed with Hitex HA-80(Hitex Co., Ltd. Japan). In addition to radiographic observation, the mandibular condyles, further decalcified and embedded in paraffin, were sectioned and stained with Hematoxylin and Eosin, Toluidine blue and Masson's trichrome. The were observed with a light microscope and a polarizing microscope. The results were as follows. 1.Soft X-ray radiograms revealed proliferation of bone after 1 week in both groups. Irregularly repaired bones and dense trabeculae were clearly observed in experimental group. 2.The resected condyles were repaired by intramembraneous and endochondral bone formation in both groups. 3.Bone tissue repair was initiated from the adjacent margin of resected bone, and cartilginous tissues were observed at the top of repaired one in both groups. 4.The number of osteoblasts of experimental group was small, compared with control group. Each osteoblast was small and flap. The thin trabeculae were irregularly formed. 5.Collagens of bone were gradually matured in both groups, but the degree of maturation was lower in experimental group. 6.Fibrous tissues covered the upper parts of repaired bone were densely arranged in the both groups. Conclusively, atrophied osteoblasts, immature collagen of bone, and this and irregular trabeculae which were characterized in the diabetes experimental group showed diabetes disturbed osteoblastic function and caused disturbance of remodeling process of bone.
